MarsEdit 3.7.11 is now available from the MarsEdit home page, and will be submitted to Apple for update on the Mac App Store.
For years, Blogger didn’t support direct photo uploads to a blog. Instead, MarsEdit uploaded photos to a photo album on Google’s Picasa Web Albums service. This was a reasonable workaround, since the same credentials used to log in to the blog could also be used to upload photos.
A few weeks ago, Google changed the behavior of the Picasa Web Albums interface that MarsEdit connects to, making it impossible to create a new album for MarsEdit photos. This means that existing MarsEdit users who had not met the quota limit for their album could continue uploading photos, but new MarsEdit users and existing users who met the quota, could not create a new album to continue uploading.
Luckily, in the years since I first added Blogger support to MarsEdit (ten years ago!), Blogger eventually added support for uploading directly to the blog-specific photo album.
MarsEdit 3.7.11 takes advantage of that access, and all photos uploaded through MarsEdit to a Blogger-hosted blog, will from this release forward be added directly to the same album as photos uploaded through the Blogger web interface.
As a special note for those who would prefer to have their photos uploaded to another Google photo album, if you locate the Google Photos album ID, you can use this long numeric value as the “Section” in MarsEdit’s photo upload details view, to upload directly to whatever album you choose (providing your Google account has permission to do so).
This update also includes a minor bug fix for users of the Japanese LiveDoor.jp service.
